I've found multiple app crashes on my Nexus S with Android 4.1.2
Main Map -> Tap on an advertisement pin (Taco Bell, AT&T, etc)
Menu -> My Waze -> Inbox -> Welcome to Waze message
Menu -> My Waze -> My Specials
Menu -> My Waze -> Scoreboard
Menu -> My Waze -> Groups
Menu -> Settings -> Spread the word -> Share on Facebook
Menu -> Settings -> Help -> Ask a question
All of the above result in either of the following error for me:
"Unfortunately, Waze has stopped."
"Unfortunately, the process com.waze has stopped."
I sent my logs around 9:51 EST.
Other minor issue
Menu -> My Waze -> Nickname; Back button does not work
